Abstract
Sanitary tissue products employing 3D patterned fibrous structure plies having a surface comprising a novel three-dimensional (3D) pattern such that the 3D patterned fibrous structures and/or sanitary tissue products employing the fibrous structures exhibit novel cushiness as evidenced by compressibility of the fibrous structures and/or sanitary tissue products, novel flexibility as evidenced by plate stiffness of the fibrous structures and/or sanitary tissue products, and/or surface smoothness as evidenced by slip stick coefficient of friction of the fibrous structures and/or sanitary tissue products, and methods for making same, are provided.
